Which therapy is commonly used to treat unconjugated hyperbilirubinemia in newborns?

• A. Phototherapy
• B. Exchange transfusion
• C. Antibiotics
• D. Vitamin K

Answer: (A)

Treating unconjugated hyperbilirubinemia in newborns focuses on making bilirubin easier to eliminate. Phototherapy uses blue light to convert unconjugated bilirubin into water-soluble photoisomers that can be excreted in bile and urine without needing the liver to conjugate it. This lowers the circulating bilirubin level quickly and reduces the risk of bilirubin-related brain injury. It’s commonly used as a first-line, noninvasive therapy for mild to moderate cases. If levels become very high or there are signs of neurological impact, more intensive measures like an exchange transfusion may be considered. Other treatments listed aren’t aimed at reducing bilirubin itself—antibiotics treat infection, and vitamin K prevents bleeding issues.
